How to prevent an android app from the apps which can make backup of .apk file.
Apps like astro file manager lets user to do so, menu: tools -> backup more info here and one can backup any installed apk on sdcard.
Later on, i can rename it to .zip and extract it, and can easily steal DRAWABLE / ASSET from that app.
My question is, How do i protect my app from such backup?
There is not, as far as I'm aware, a full-proof method to stop this. But even so, I would always ask myself before going to the effort of trying whether I even really care if some one tries to steal something from my app. I spend my effort on making sure any data is secure.
